Is it possible to connect to on-premises Oracle DB using Azure Data Factory via a Site to Site VPN? Or am I obliged to use a Self-Hosted Integration Runtime?
Thanks
If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.
If your data store is a managed cloud data service, you can use the Azure Integration Runtime. If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list.
You can also use the managed virtual network integration runtime feature in Azure Data Factory to access the on-premises network without installing and configuring a self-hosted integration runtime.
For more information about the network security mechanisms and options supported by Data Factory, see Data access strategies.
The integration runtime provides a built-in Oracle driver. Therefore, you don't need to manually install a driver when you copy data from and to Oracle.

We have to migrate the Oracle Secure Global Desktop application on Azure cloud.
So, My question is as below-
Is it possible to migrate above application on Azure cloud ?
If we plan to migrate it what thing I have to take care?
Regards,
Abhi
Yes, you can connect Oracle Secure Global Desktop with Azure cloud as the oracle have partnered with Microsoft with the private connectivity by enabling VPN access.
For private access from your data center to Oracle Cloud, use either Oracle Cloud Infrastructure FastConnect or IPSec VPN. Similarly, for private traffic from your data center to Microsoft Azure, use ExpressRoute or VPN.
For cross-cloud networking between Oracle Cloud and Microsoft Azure, set up a connection between a FastConnect circuit in Oracle Cloud and an ExpressRoute circuit in Microsoft Azure.
you can connect through Microsoft Azure Virtual Network and Express Route

I need to connect to on-prem Oracle Database using Azure pipeline. I have created self-hosted agent which runs on the same subnet as the database. I have created a deployment group as well. However, I am not able to find a task that I could add as a stage to the release pipeline that could authenticate the db server using the credentials and run a GET query to pull data. Am I on the right track? Are there other alternatives? Thanks.
please use data factory in Azure to connect Oracle database on-premise. Yes, you should install a self-host Integration runtime for data factory. setup "Linked services" in data factory, so that you can input the credentials/connection string there.

We are trying to use Azure Data Factory SSIS Integration Runtime service to run a set of existing SSIS packages (basically to transfer data from oracle to SQL Server).
However, when deploying, there is a validation error saying "Package xxx: Connection xxx contains unsupported provider."
We tried using the following two providers in the SSIS packages, both of them were reported as unsupported:
"Oracle Provider for OLE DB"
"OracleClient Data Provider"
What are the supported providers for accessing Oracle in ADF with SSIS IR?
When connecting to Oracle using a provider such as "Oracle Provider for OLE DB" we need to install that to the node(s) running SSIS IR. This can be done by customizing the SSIS IR using the portal.
https://learn.microsoft.com/en-us/azure/data-factory/how-to-configure-azure-ssis-ir-custom-setup
Steps summary:
Download and edit the sample script (main.cmd) provided in the above
link (from the publicpreview container)
Upload it with the ODAC122010Xcopy_x64.zip file to an Azure
Blob Container.
Get a "Shared Access Signature" uri for this folder.
Shutdown SSIS IR.
Go to customize the SSIS IR and provide the link copied.
Restart SSIS IR.
Your SSIS package is access on-premise local Oracle DB.
As you know, Azure can not connect to on-premise resource directly. For example, when we need access the local SQL server, we must use Self-host integration runtime.
When deploy it to Azure and run the package in Data Factory, you will get the error.
We can get the reason from the document: Azure-SSIS Integration Runtime:
Azure-SSIS IR network environment
Azure-SSIS IR can be provisioned in either public network or private network. On-premises data access is supported by joining Azure-SSIS IR to a Virtual Network that is connected to your on-premises network.
The solution: Join an Azure-SSIS integration runtime to a virtual network:
If your SSIS packages access data stores/resources that allow only specific static public IP addresses and you want to secure access to those resources from Azure-SSIS IR, you can bring your own public IP addresses for Azure-SSIS IR while joining it to a virtual network and then add an IP firewall rule to the relevant resources to allow access from those IP addresses.
I'm sorry I can't test it for you because I don't Oracle environment.
Hope this helps.
Trying to connecting to On-Premises Oracle DB from Azure Data Factory.
Current Setup:
Oracle db - On Premises
VM with Self Hosted Integration Runtime on Azure - Tested with other MSSQL Server Databases - can connect successfully - This VM is managed by ITP (our Cloud Hosting Team), developers don't have access to it.
Azure Data Factory - configured to consume above Self Hosted Integration Runtime.
I can connect to Oracle db from my local machine, using Taod for Oracle. When passed same credential details - connection fails from ADF.
Do I need to ask ITP to install ODAC on VM for the connectivity?
Congratulations that #Sreedhar have figured out the error by himself:
"Figured out, just need to install Oracle Data Access Components (ODAC) on the VM and everything works."
I help him post it as answer and this can be beneficial to other community members.
Is there any cloud computing service like e.g. Google's AppEngine or Amazon's S3 out there, that allows me to use JDBC without using some sort of proxy? I do have a MySQL server, that I can't move into the cloud, so I want to access this server directly via a JDBC connection.
If you can't migrate your database, don't move to the cloud. It would be a performance and security nightmare to have your app communicate with the database over the internet.
To answer your question more specifically:
S3 is a storage platform, so it is irrelevant to your question. Google's App Engine is only designed to interface with it's own storage system.
If you really want to do this you could use a full fledged virtual instance such as Amazon EC2, or Rackspace Cloud.
EDIT
I forgot to mention, Google now offers a MySQL service. I would assume that Java apps use jdbc to connect to it.
